You should expect to be committed to a psych ward, assuming anyone finds out, or if you've warned anyone, some hopefully minor liver damage, and probably some degree of serotonin [shock] syndrome.
You definitely shouldn't take anything else, as anything else that actually kills you would be fatal on it's own, and I'm betting you don't have anything like that.
Ride it out, and assuming you're serious and still want to CtB once you're through this, do your research and due diligence and pick a method that has a significant chance of success.
